Major League Baseball apparently feels the same way. Pat Courtney, MLB's senior vice president of public relations, issued the following statement on Thursday:

"We cannot draw any conclusions from this video. There were no complaints from the Cardinals and the umpires never detected anything indicating a foreign substance throughout the game."

That about sums it up. If the Cardinals didn't complain and the umpires didn't notice anything, there's really nothing that can be done. It's worth noting that a lot of times, opposing teams will keep quiet because they don't want their own pitchers to get checked out for foreign substances. It's one of those things that could have unintended consequences, I suppose.
